Answer: He still has to mow 45 lawns, or 75% of the lawns before he is finished.
Answer: 1. -11=x 2. 24=x 3. x=-12 4. -7 5. x=7
Step-by-step explanation: The answer to first one can be calculated by seeing the - as a -1.
-5 = x - (-6)
-5=x+6
Then subtract 6 from both sides.
-5=x+6
-11=x
The answer to the second can be found simply by dividing both sides by 1.25.
- 30=1.25x
-30/1.25=1.25x/1.25
24=x
The third one can be solved by as we said before dividing both sides by -6.
-6x=72
-6x/-6=72/-6
x=-12
The fourth one can be found again by using division on both sides.
-4.9=0.7x
-4.9/0.7=0.7x/0.7
-7=x
Finally we solve the last one by again doing the same thing dividing both sides by 0.45.
3.15=0.45x
3.15/0.45=0.45x/0.45
7=x
Hope this helps!
The hypotenuses, is what I believe you're referring to.
<span>The other two are at a 90 degree angle to each other. There is no side
that is always adjacent, you just say adjacent if the side happens to be
right next to an angle you are describing. Same with opposite, it is
the one side that doesn't touch the angle you are describing.</span>
The zeros of this function is when y = 0.
(x, 0) and (x,0)
Looking on the graph
It would be (3,0) and (6,0)
The solution is x = 3, x = 6
Answer:
Step-by-step explanation:
The cotangent of theta is:
For pi/2 < theta< pi
This means that the angle is in the second quadrant. In the second quadrant, the cosine is negative and the sine is positive. This means that the cotangent will be negative.
Secant:
In this question
So
Using cross multiplication
Now we apply the following trigonometric identity:
Since the angle is in the second quadrant, the sine is positive.
Finally, the cotangent:
